IMPROVEMENTIIN MACHINES FOR SHELLING CORN.

.l'he Schedule i'efenedtoin these Letters Patent and making part of the same.

To whom it may concern: I

Be it known that we, JAMES MILLER and NAPo- LEON DUBRUL, of Joliet, inthe county of Will and State of Illinois, have invented a new and useful Im'r provement in (lorn shellers; and we do declare that the following is a trne and accurate description'thereof, reference being had to the accompanying drawing I and to the letters of reference marked thereon and being a partIof thisspecification, in which Figure 1, plate 1, is I a vertical section of our improved corn-sheller. j ;I I I I I I I y Figure 2, plate 2, is a horizontal section taken on thelinexminfigrl'g I a P I Figure 3 is adetached sectionalview of the car- I Tier-shell taken on the linejIy y in fig. 1; and

Figure4 is a perspectiveview of the machine. Like letters indicate likeparts in eachfigure. This invention relates to an improvement in' machines for shellingI corn and I It. consists in the peculiar construction and arrangement of arag-piece inlthe hopper for removing a por.-

I tion of the corn from the jcob as it descends; in the I peculiar combination and arrangement of the carriershell withI'I relation toth'e picker-wheel; and in the I general arrangement of the various parts, as more fully hereinafterset forth. In the drawing- I I A represents the frame and external casing of our I machine, which is constructedof end'pieces A, lower side pieces A, properly secured to saidend pieces, and cast-iron shaft-beds A, which rest upon and are, secured to said side pieces through an overhanging flange, Ia, resting against the outsides of said side pieces I I The shaft-beds above named are further secured in place by means of wings upon their ends, whichfit I into corresponding grooves a? in said end pieces A.

Restingeupon these shaftbeds are the upper side I pieces A, which slide in and are secured byflsaid groovesd". LI 1 B and Oarejshafts transversely journaled in boxes, thelowerparts BI' of which are cast in and with said I 'shaft-bedsIA, and the upper parts are of usual construction. I

D is a hopper at the top of the case, discharging between the two shafts.

E is a toothed wheel keyed to the shaft-3B, and re- F is a picker-wheel, being a disk studded with projecin'pgp'ointson one face,vin concentric lines.

On the oppositeface fthereofyis a spurgear, a,

which engages with a pinion, IG, secured to the shaft B.

' The shaft 0 is rotatedbya hand-crank, 0', audio turn rotates the shaft B, which is providediwith a fly- Iwheel, H, at one end, and at the other with a pulley,

I, which, in turn, rotates the shaft of the blast-fan J in the fan-case below, through a belt passing round its pulley J.

K is the carrier-shell, in the general form of a hollow segment, secured at]: b to the side of the machinecasing, open at each end and the side next the pickerwheel. The discharge end of the shell has its upper portion curved downward as it approaches the picker- I Wheel, and is provided with serrations to project between the concentric lines of projections on the pickerwheel.

L is a door hinged on the face of the shell near itsdelivery end, and is pressed inward bya spring, M.

N is a rag-piece hinged to the. top flange of the hop- I per, lying on it and projecting below it, the lower end being serrated, as shown in fig. 1. I

An elliptic spring, N, placed upon the upper part of said rag-piece, and adjusted by means of a belt, I

N, provided with a thumb-nut passing through sad- (1168 N attached to said spring in its center, and through said rag-piece and through the hopper D ep- Ierates with and in connection with a spring, 0, here after mentioned.

AI spring, O, interposed between it and an arm, P, secured by a screw, S, to theshank it of the shell K, presses it toward the rag-wheel E, which, be

ing'revolved in the direction shown by thearro'w ih fig.

1,catches the cob as it issues from the hopper and draws it down, the serrations of the rag-piece tearing I off a ccnsiderable portion of the corn from the cob, which is rotated in the triangular spaceformed by the two wheels and the rag-piece, the kernels'ialling on a grain-board below, forming the fan-case; falling over the end of which they cross the blast, which blows away the chaff through the spout T, while the grain finally passes down to the floor or into a drawer in the lower part of the frame; the cob passes along, into and through the carrier-shell, until nearly through, when it is pressed, by the door L, against the pickerwheel, which removes any-adhering kernels in the rotation of the cob at this point, which rotation is effected by the beveled or curved upper arm c' of the I shell and the forcing of the cob against the pickerwheel, as shown in fig. 3. This is an important function in the'rnachine, as every part of the cob in its rotation is brought forcibly into contact with the picker-wheel, removing every adhering kernel, which,

rolling down the shell until reaching the plain part of the picker-wheel, falls through and down past the blast.

We do not wish to confine ourselves to the particular form or arrangement of the door and rag-piece springs shown, as others may be employed.

What we claim as our invention, and desire to secure by Letters Patent, is-

1. In combination with the hopper D and rag-piece N, the springs- N and O, constructed and arranged.

substantially as described and shown.

2. The combination and arrangement of the spring 0, arm P, and rag-piece N, as and for the purpose herein specified.

3. The combination of the carrier-shell K, constructed with the upper beveled portion 1 and the picker-wheel 13, both constructed and arranged substantially as described and shown.

4 The combination of the door L, the carrier-shell K, and the picker-wheel F, when said parts are con- Witnesses:
